Apparatus and method for inspecting a turbine blade tip shroud

An apparatus for inspecting a turbine blade tip shroud, the apparatus comprising:

• a frame comprising a top surface and a bottom surface that is alignable with the turbine blade tip shroud;
• a first z-notch inspection slot that passes through the frame from the top surface to the bottom surface and is positioned to align with a first z-notch of the turbine blade tip shroud when the frame is aligned on the turbine blade tip shroud;
• a first removable z-notch inspection insert comprising a first cross-sectional profile substantially matching the first z-notch inspection slot and comprising a first z-notch guide face that faces the first z-notch of the turbine blade tip shroud when the first removable z-notch inspection insert is passed through the first z-notch inspection slot;
• a second z-notch inspection slot that passes through the frame from the top surface to the bottom surface and is positioned to align with a second z-notch of the turbine blade tip shroud when the frame is aligned on the turbine blade tip shroud;
• and,
• a second removable z-notch inspection insert comprising a second cross-sectional profile substantially matching the second z-notch inspection slot and comprising a second z-notch guide face that faces the second z-notch of the turbine blade tip shroud when the second removable z-notch inspection insert is passed through the second z-notch inspection slot.
